Fields of application

weber.therm 377 is a high-yield, cement-free, ready-to-use dispersion-based reinforcing mortar for the Etics (external composite thermal insulation system) weber.therm B 200.
The system consists of following components: polystyrene insulation board weber.therm EPS, bonding mortar weber.therm 309 (on concrete) or 370 (on specific building panels), reinforcing mortar weber.therm 377 + woven mesh weber.therm 311, dowels weber.therm and thin-layer mineral (EN 998-1) or organic overlay render (EN 15824).
Particularly suitable for the facade insulation of buildings whenever a slim system structure is required.
Ideal as renovation mortar for old load-bearing overlay renders thanks to its high crack resistance.
Can also be used for the renovation of damaged and cracked new and old facades.
For use outdoors.

Main features

• high bonding strength
• flexible reinforcement layer
• excellent workability properties
• solvent-free
• dedicated for thin-layer applications
• provides a high-performance reinforcement layer in combination with the reinforcement fabric weber.therm 311
• resistant to weathering
• creamy consistency
• for use as reinforcing mortar for Etics weber.therm B 200
• also as renovation mortar for renovation of damaged and cracked new and old facades (old load-bearing overlay renders)

General notes

• Limits of use: weber.therm 377 is not suitable for bonding insulation boards; in this case, use the special cement-based bonding mortar 370.
• Comply with the national guidelines and/or standards (for ex. DIN 18550); if not issued and if necessary, request technical advice.
• The consumption figures mentioned in this document refer to the minimum layer thickness of the mortar. Due to specific substrates and application variations the consumption might vary. Exact consumption must be determined on a job site mock-up (trial area).

Special notes

• Cover adjacent components well or protect against splashes.
• In case of renovation of old facades, a 2-layer application with intermediate drying and embedment of reinforcement fabric may be required.
• For full information related to all application details, like assembly of boards, dowelling works, reinforcement of corners, assembly of profiles, socket parts, etc., request technical advice.
